Since I don't think anyones said it Rin from Shuffle had things bad. Not the worst, just about everyone in Elfen Lied probably takes that. Still after you have your parents horribly killed in a car accident, guess who gets to live with a psyco who spends her every waking moment trying to either torture, or straight up murder him. Not the worst and things do get better but still...

Even the person with the picture of Killua didn't mention him?! Physically and mentally tortured and made to kill people. I think that beats people don't like me because I have a demon in me and my big brother killed my entire clan combined.
